 In the VECTO simulation, the IEPC component is virtually split up into the electric machine (with gear-dependent electric power maps), an APT-N gearbox in case of a multi-speed gearbox or a single-speed gearbox in case the IEPC has only a single fixed transmission ratio, and optionally an axle gear. All virtual powertrain components (gearbox, axlegear) are modeled as loss-less components. Thus, the simulation of an IEPC is similar to E2 vehicles in case of a multi-speed gearbox or an E3 vehicle in case of a single-speed gearbox.
